` specification of Letters Patent N0.`12,s59, dated May 15, 1855.

A, is the oil cup'arranged on the connecting rod as shown directly over the crank pin; B, is the screw top or cover, C, the valve and D, the screw for regulating the movement of said valve., a, is the. discharge through which the oil passes from the cup rto the crank pin. The vvalve C, `is made with two stems ZJ, c, of triangular Vshape which 'fit in guides CZ, e, formed in the top and bottom of the cup. By these stemsthe valve isalways kept in its place and as the stem 6, is of triangular shape the oil has a Achance ,to escape when the valve is raised off its` seat f, `as shown in black.

Operatiom As the connecting rod moves back and forth it causes the oil cup which is vattached fast to it to move with great velocity and in doing so` `the valve is, by

4reason of the motion of the connecting rod `being quicker than gravitation, caused mincrease the quantity supplied the screw must be turned to the right and vice versa whenit `is desired to lessen the quantity.

By my invention a `constant but at the same time not too liberal a supply of oilis kept up, and the necessity of employing a wick which is liable to become cloggedV by the oil becoming gummy and intime prepin vbeing properly lubrivent the ycrank cated, is avoided. h

\ WhatI claim as my, invention and desire to secure by Letters Patent, is-

structed, arranged and operating substantially as herein described.
